Why Do Onions Make Us Cry?

Onions are one of the most common staple foods around the globe. Ironically, for a vegetable so delicious, they can often be tear-jerkers.

Read on to learn why onions cause your eyes to tear and sting, and what you can do to minimize discomfort.

Why Does Cutting Onions Cause Tearing?

Onions produce a sulfur compound called propyl sulfoxide that is stored in the cells of the onion bulb (the part of the onion we eat). Onions grow underground, where they can be eaten by all types of creatures. This odorous sulfuric compound acts as a deterrent to small animals with big appetites.

When one slices into an onion and breaks open its cells, the sulfur compound is released and mixes with the moisture in the air — turning it into smelly and irritating sulfuric acid. When this chemical rises up and comes in contact with your eyes, it stings!

To keep your eyes from potentially being damaged from this chemical exposure, your brain triggers your eyes to tear and flush out the irritating gas particles. Once enough tears have flushed out the sulfuric acids particles from the eye, clear vision and comfort is usually restored. Although your eyes may sting and feel unpleasant, symptoms are temporary and the sulfuric acid won’t damage your eyes.

How Can I Reduce Eye Discomfort When Chopping Onions?

Most experienced chefs will tell you that chilling your onions in the fridge for at least 30 minutes before slicing them will reduce the amount of tearing they cause. Propyl sulfoxide escapes slower in cooler temperatures, reducing the amount of sulfuric acid in the air.

You can also try cutting the onions at arm’s length, or direct the odorous air away with a small fan. Some say that chopping onions immersed in water also helps. Another option is to wear kitchen goggles to protect your eyes.

Furthermore, try to use fresh onions whenever possible. The longer an onion has been stored, the more likely it will induce tearing and discomfort. Try to avoid slicing near the root end of the bulb, as that area has the highest concentration of sulfuric compounds.

If you frequently suffer from eye irritation — and not just while cutting onions — we can help. At Yesnick Vision Center, we treat a wide range of eye conditions and can provide you with the treatment and relief you seek.

Emergency Eye Care vs. Routine Eye Care

Your eye is red and painful, your eyelid is swollen and vision seems blurred. Should you call our local Las Vegas eye doctor for an urgent eye exam? Or is it enough to book an appointment for a later, more convenient date? Many people are unsure about what to do when eye problems arise. Let’s discuss the difference between routine eye care services and emergency eye care, so you know the best action to take.

Our Las Vegas eye doctor can provide the help you need for a wide variety of emergency conditions. This is particularly significant for keeping you out of the hospital emergency room – and away from exposure to all the germs circulating in the hospital waiting room.

Conditions that Require Emergency Eye Care

If you experience any of the following, our eye doctor recommends contacting our Las Vegas optometry office to schedule an urgent eye exam.

  • Eye injury or trauma, such as getting hit in the eye
  • Chemical burns
  • Sudden onset of blurry vision
  • Sudden loss of vision
  • Corneal scratches
  • Seeing floaters or flashes of light
  • Oozing discharge, red eyes and eye irritation
  • Foreign object stuck under your eyelid

Some types of dangerous eye emergencies will require a trip to the hospital, such as:

  • When your eyes are dilated unequally or if they suddenly don’t move in coordination
  • A foreign object pierces your eye surface and/or you have bleeding from your eyeball
  • Severe headache with visual effects

Common Routine Eye Care Services

If your eyes are feeling itchy or dry, it can be very annoying, but it’s not classified as an emergency. You need to book an eye exam for diagnosis and treatment, but there’s no urgency.

The same protocol applies for your yearly eye exam, evaluation of visual acuity, or a contact lenses follow-up fitting. These visits to the optometrist are all necessary, but they can wait until it’s convenient for you to come in for your next eye doctor’s appointment.

At Yesnick Vision Center, we put your family’s needs first. Talk to us about how we can help you maintain healthy vision. Call us today: 702-500-0525 or book an appointment online to see one of our Las Vegas eye doctors.

Can Eyeglass Lenses Add Zing to Vision for People with Color Blindness?

If you have color blindness, it doesn’t mean you suffer from blindness. Really, it’s a vision condition that can dull your view of the vibrant world, making it impossible to see all the colors of the rainbow.

Color blindness is largely genetic and relatively common, affecting millions of people worldwide. Until recently, it had no effective treatment. But the innovative partnership of a UC Berkeley mathematician and researcher in perceptual psychophysics with a renowned glass researcher changed the status quo. This scientific team developed EnChroma eyeglass lenses for people with color blindness.

Our Las Vegas eye care center team has witnessed the amazing reaction of many color blind patients the first time they put on new eyeglasses with EnChroma lenses! To try them on for yourself, book an appointment with our optometrist near you.

What are color blind eyeglass lenses?

These specially tinted lenses can help a person with color vision deficiency to perceive colors more precisely. While purchasing a pair of new glasses with color blind lenses won’t “cure” color blindness, it can enliven vision by offering colorblind wearers the chance to see a wider spectrum of colors while the glasses are on.

How do color blind lenses work?

Made from advanced optics, these lenses filter out certain wavelengths of light – so the light that enters your eye has a more accurate ratio of wavelengths. Because lighting conditions change from morning to night, color blind eyeglass lenses come in outdoor and indoor versions to function optimally where you need them most. If you require prescription lenses to see clearly, new glasses with EnChroma lenses can also be crafted with your prescription. Alternately, you can wear lenses that fit over your existing glasses.

How can new eyeglasses with color blind lenses help me?

There are a variety of ways that these eyeglass lenses can improve your life. If you’ve always relied on others to make sure your clothes match, these new glasses can finally give you the confidence to get dressed on your own! The changing colors of traffic lights will finally be clear, and you’ll gain a new appreciation for your flower garden. Food may also look more appealing, and you’ll be able to tell the difference between ripe and unripe produce.

Are there different types of eyeglass lenses for color blindness?

Presently, EnChroma lenses are the most widely used lenses for color blindness. In particular, these lenses are helpful for distinguishing between hues if you have red-green color blindness. According to EnChroma, about 80% of all people with a color vision deficiency can be helped by these lenses. The only way to determine if they can help you is by giving them a try!

When you purchase a pair of new eyeglasses from our Las Vegas optical store, the optometrist near you can fit them with specialty eyeglass lenses for color blindness to energize your color vision and brighten your perspective on the world!

Pink Eye? It Could Be Coronavirus

How to prevent conjunctivitis and protect your eyes

When you have a virus, especially one that causes a hacking cough, runny nose, and other symptoms of a common cold or flu, it’s typical for your eyes to also get puffy and red. You may be suffering from viral conjunctivitis, also known as pink eye.

How do viruses get into your eyes?

It’s rather simple. When you’re sick, you can easily transfer viruses to your eyes by sneezing, coughing into your hands, or blowing your nose – and then touching the area around your eye.

The coronavirus – pink eye connection

According to the American Academy of Ophthalmology (AAO), doctors have discovered that COVID-19 can cause conjunctivitis. If you’re standing within six feet of an infected person, and they cough or sneeze, the virus can enter your eye. Alternatively, if someone sneezes and virus particles land on the shopping cart that you take and push around a store, and then you touch your eyes without washing your hands first – you’re giving the virus direct access.

However, despite the apparent ease with which coronavirus can infect eyes, the AAO reports that only about 1 – 3% of all patients with the virus contract pink eye.

Preventing pink eye

Like always, prevention is the most effective medicine! Eye care professionals recommend following these tips to help prevent getting viral conjunctivitis:

  • Wash your hands correctly

The CDC instructs people to wash their hands in accordance with these steps: wet your hands, turn off the tap, apply soap, lather and scrub for 20 seconds, turn on tap and rinse. Air dry your hands, use a disposable paper towel and discard it immediately, or use a clean (not shared) towel.

  • Keep your fingers away from your face

No rubbing or wiping your eyes! Even if you don’t feel any symptoms of coronavirus, it’s essential not to touch any part of your face. To wipe away tears or remove makeup, use a clean tissue.

  • Don’t share your personal things

As generous as you may feel about letting others use your personal items, now’s the time to keep things to yourself. For example, the CDC recommends not sharing eye drops, makeup, makeup brushes, contact lenses cases, pillowcases, or towels. Pink eye is highly contagious.

  • Consider wearing glasses instead of contacts

While there’s currently no evidence to prove that wearing contacts raises your risks of contracting the novel coronavirus, there’s some evidence that shows you can get Covid-19 by touching a contaminated surface and then touching your eyes. In general, contact lenses wearers touch their eyes more often than people who wear eyeglasses, so it may be smart to make a temporary switch from contact lenses to glasses. However, this is only a friendly recommendation and not a hard-and-fast rule. If you prefer to stick with wearing contacts, washing your hands thoroughly can help keep you and your eyes safe.

Treatment for conjunctivitis

Regardless of whether your pink eye is caused by coronavirus or a different virus, there is no treatment for viral conjunctivitis. Usually, it goes away on its own within one to two weeks.

To alleviate your painful symptoms, eye doctors recommend:

  • Taking an over-the-counter pain medication, such as acetaminophen, ibuprofen or any anti-inflammatory drug
  • Applying a warm compress on your eye for a few minutes; take care to use a clean wash cloth each time and for each eye
  • Use artificial tears (lubricating eye drops) to soothe your eye irritation; don’t touch the bottle tip to your eye

Are you sick and have pink eye symptoms?

Now is not the time to make a DIY diagnosis. Eye redness, even if you have a virus, doesn’t necessarily indicate that you have conjunctivitis. A wide range of other conditions can lead to the same symptoms. Contact an eye doctor near you for help to figure out what’s causing your eye pain. Don’t visit your eye care practice without calling for guidance first, because extra precautions must be taken with patients who may have COVID-19.

Glaucoma Treatment: Medication or Surgery

Various treatment options are available for glaucoma, including medicated eye drops, laser procedures, and traditional surgery. The shared goal of all glaucoma treatments is to lower eye pressure, which protects the optic nerve from damage and prevents vision loss. If our Las Vegas, Nevada, eye doctor diagnoses you with glaucoma, possible treatments include:

Eye drops

Generally, the first choice for treating patients with glaucoma is eye drops. This medication works to decrease eye pressure by helping the eye to drain fluid more efficiently and/or by decreasing the quantity of fluid produced by the eye.

Several types of eye drops for glaucoma are available, classified by their active ingredient. They include beta blockers, prostaglandin analogs, carbonic anhydrase inhibitors, alpha agonists, and rho kinase inhibitors. Sometimes, people need to use a combination of more than one type of medication.

Oral medicine

When eye drops can’t lower eye pressure sufficiently, an oral medication may also be prescribed. These drugs are associated with specific side effects, such as an upset stomach, frequent urination, kidney stones, and tingling in the fingers and toes.

Surgery

When medication alone is not enough, surgery may be an excellent alternative. At our Las Vegas, Nevada, eye care center, we provide expert co-management for glaucoma surgery. Our eye doctor will work in collaboration with your eye surgeon to provide comprehensive preoperative and postoperative care.

The risks of surgery include red eyes, eye pain, eye infection, vision loss, inflammation, and intraocular pressure that’s too low or too high. Different types of surgeries can improve fluid drainage within the eye, and our Las Vegas, Nevada, eye doctor will discuss which procedure is best for you.

  • Laser surgery to open clogged ducts in the trabecular meshwork is typically the primary treatment used for open-angle glaucoma. It can delay the need for taking medication, saving the patient from the possible side effects. Selective laser trabeculoplasty (SLT) and argon laser trabeculoplasty (ALT) are the most common laser surgeries for glaucoma.
  • Filtering surgery (trabeculectomy) works by making an opening in the white of the eye.
  • Drainage tubes may be implanted in the eye.
  • Minimally invasive glaucoma surgery (MIGS) has less risks than other types of surgery and requires less immediate postoperative care.
  • Laser peripheral iridotomy can be used to treat acute angle-closure glaucoma, which is a medical emergency. This procedure involves using a laser to make a small opening in the iris for fluid to flow out from.

If you are treated for glaucoma, you will need to visit our eye doctor for regular follow-up eye exams and monitoring to keep watch on your intraocular pressure. If it is elevated, a new treatment plan or a referral to your eye surgeon to assess the need for repeat surgery may be recommended.

Cosmetic Contact Lenses Can Hide Visual Disfigurement & Revitalize Your Life

Revolutionary prosthetic contacts can be the ultimate aesthetic solution

When most people hear the term “contact lenses,” they think of a convenient way to correct vision – an effective alternative to eyeglasses. However, contact lenses have purposes that go beyond giving 20/20 vision. Cosmetic contact lenses, also called prosthetic contact lenses, are a type of eyewear that’s also intended for covering up ocular disfigurements. These specialty contact lenses can be life-changers: enhancing appearance, boosting self-confidence, and enhancing quality of life for people with eyes that don’t look normal or healthy.

At Yesnick Vision Center, we fit patients with all types of contact lenses, including prosthetic contact lenses; schedule a consultation at our Las Vegas, Nevada, eye care center to learn how we can transform your look with cosmetic contact lenses.

What disfiguring eye conditions can be helped with contacts?

Certain eye conditions or injuries can damage the cornea or other parts of the eye in a way that causes disfigurement. Problems that may lead to an eye deformity include:

  • Eye trauma
  • Eye infections
  • Surgical complications
  • Retinal detachments
  • Glaucoma
  • Sjogren’s syndrome
  • Herpes in the eye
  • Congenital defects (eg. aniridia – being born without an iris, or albinism)
  • Being born with strange pigmentation around the cornea, or a bluish, cloudy cornea

How are these kinds of visual disfigurement treated?

Specialty prosthetic contact lenses can be an ideal solution for hiding eye deformities. If you have a refractive condition, these cosmetic contacts can also improve your vision quality. Basically, they are made with an opaque design that mimics the natural appearance of the eye, instead of being transparent like standard contact lenses.

When we fit patients with cosmetic contact lenses, our Las Vegas, Nevada, eye doctor uses corneal topography to measure the corneal curvature for a comfortable fit. We also consider the color, shape, hue, and details of the person’s natural eye – in order to design these custom contacts to be as close a match as possible.

When the cosmetic lens is worn, the disfigured eye will appear totally normal to outsiders. People who used to be self-conscious about appearing in public no longer have to worry about attracting stares. They can live normally, without constant embarrassment and with a healthy sense of self-esteem.

Do prosthetic contact lenses have a function beyond being cosmetic?

Yes, prosthetic lenses can also enhance visual acuity, comfort, and ocular health. If you have a visibly deformed eye, you may still have vision in that eye but struggle constantly with symptoms such as light sensitivity, color blindness, reduced visual contrast, double vision, or other side effects. In addition to sharpening your vision, cosmetic contacts can be customized to control how much light enters your eye, reduce glare, and maximize your overall vision quality.

If you have an eye condition that allows too much light to reach the back of your eye, such as albinism or aniridia, prosthetic contact lenses also protect your eye health by blocking UV rays from causing damage.

What Is 20/20 Vision?

If your last eye exam revealed that you have 20/20 vision, you probably walked out of the eye care center with a big smile! It’s a great feeling to be able to see without eyeglasses or contact lenses. However, did you know that 20/20 vision is not the same as having perfect vision? So what is it?

At Yesnick Vision Center, when Dr. David Yesnick announces the results of your eye exam, he is reporting on your visual acuity, which is the clarity of your eyesight. These numbers describe how well your eyes can see an object that’s 20 feet away. If you can see it clearly, then your vision is considered “normal” – but not “perfect.” That’s because even if you have 20/20 vision, you could still have problems with peripheral vision, color vision, eye coordination, focusing, or depth perception. To find out your visual acuity and total eye health, book an eye exam with our Las Vegas, Nevada, optometrist near you.

How does my eye doctor test visual acuity?

Typically, every eye exam and vision screening includes having you read the Snellen Eye Chart. This diagnostic tool appears as lines of block letters and numbers printed in progressively smaller sizes. The first line will display one huge letter, such as an “E”, and as you move down the chart row by row, the letters get smaller, and there are more of them per line. The lower down on the chart you can read correctly, the closer you are to being diagnosed with 20/20 vision. The bottom row (eight down) is 20/20 vision.

What if I don’t have 20/20 vision?

Don’t worry, you’re in good company! Statistics say that almost half of US adults don’t have 20/20 vision.

Depending on what your visual acuity is, you may need vision correction with prescription eyeglasses, contact lenses, or LASIK refractive surgery, to help you achieve 20/20 vision, or close to it. But not everyone can get to 20/20 – even with corrective treatment. In other words, some people can only see at 60 feet what others with normal vision can see at 20 feet (=20/60 vision). However, that doesn’t mean you can’t see well enough to function. For example:

  • If our eye care professional detects that you have 20/40 vision, it’s still enough to get a driver’s license.
  • If you have 20/80 vision, you should still be able to read headlines in a newspaper and tell the time on an alarm clock placed 10 feet away.
  • If your visual acuity deteriorates to 20/200 vision, you’ll be classified as legally blind.

Can I have better than 20/20 vision?

Sure, especially if you’re a bird of prey! Falcons see about eight times better than humans, with a visual acuity of about 20/2. All jokes aside, even humans can have vision that’s sharper than 20/20, such as 20/15. That means you can back up five feet during your eye exam and still read the Snellen eye chart the same as a person with normal vision standing five feet closer to the chart.

Why do I need good vision?

There are lots of reasons why it’s smart to invest in good vision by visiting our Las Vegas eye care center near you for regular eye exams. Don’t underestimate the value of sharp, healthy vision in your life! Here are a few important benefits of 20/20 vision:

  • Reading with ease: reading is essential for day-to-day life, whether you read the newspaper, your smartphone, documents at work, letters and bills, or just want to enjoy a good novel.
  • Comfort: without sharp vision, you’ll need to squint all the time, leading to headaches and muscle strain.
  • Safety: activities such as driving and biking become extremely hazardous if you can’t see. Even if you’re just taking a walk, having sharp visual acuity will help prevent you from tripping and falling.
  • Quality of life: clear eyesight goes far towards your quality of life! Without sharp vision, who knows what scenes and wonderful moments you’ll miss out on?

At Yesnick Vision Center, we’ll help you to see the best that you can see! Contact our Las Vegas, Nevada, optometrist to schedule an eye exam near you today.

Tips on How to Take Care of Your Eyes

Guidelines from your eye care specialist in Las Vegas, Nevada

There are many routine daily actions you can take to preserve your eye health and keep your vision crisp and clear. By following a few simple practices outlined below, you can reduce your risk of developing many common ocular diseases and vision problems.

Book regular eye exams

First and foremost, visit your local eye doctor for a comprehensive eye exam near you. This is the most significant way to take care of your eyes. It is typical to have a problem and not know about it, because many eye diseases don’t present with symptoms during the early stages. Once your eye care provider detects the signs of an ocular condition, you can receive treatment – and early treatment goes far towards preventing vision loss.

Be aware of your risk factors for eye diseases

Normal aging raises your risk of certain eye diseases. Additionally, your risk is higher if you:

  • Are obese or overweight
  • Have a family history of ocular disease
  • Are African American, Native American, or Hispanic
  • Have diabetes or high blood pressure

Some ocular conditions run in families, so it’s important to speak with other family members to find out about any eye problems. Then, visit a center for eye care near you to discuss your personal risk factors. The optometry team can inform you about various ways to decrease your chances of developing specific eye diseases.

Make healthy lifestyle choices

Eyes are a part of your whole body, and protecting your overall well-being can help safeguard your vision too. Healthy habits are essential, such as eating nutritiously and being physically active. These behaviors can reduce your risk for diseases that can lead to vision problems, such as high cholesterol, high blood pressure, or diabetes. Our eye doctor in , Nevada, shares the following guidelines for taking care of your whole body:

  • Be active: regular exercise and cardiovascular physical activity are effective ways to keep yourself healthy
  • Eat well: include plenty of dark, leafy greens in your daily diet, such as spinach, arugula, collard greens, and kale. Foods that are high in omega-3 fatty acids, such as salmon, halibut, and tuna are also recommended for healthy eyes.
  • No smoking: smoking increases your chances of developing eye disease, such as cataracts and macular degeneration, and it can also damage the optic nerve.

Use eye protection

Everyone knows about the need to slather on sunscreen before spending time outdoors, but many people neglect to give their eyes the same attention.

  • Wear sunglasses and sunwear: choose sunglasses that block 100% of UVA and UVB radiation, and wear whenever you’re outdoors, even on cloudy days. Hats with a visor are also helpful at blocking the sun’s rays from reaching your eyes.
  • Let your eyes rest: gazing at a computer screen for hours on end can lead to eye fatigue. Give your eyes a break by looking at something 20 feet away, every 20 minutes for 20 seconds.
  • Put on safety glasses: certain activities, such as playing sports, doing home repairs, and working in construction all expose your eyes to potential hazards. Protect your eyes from injury by wearing safety glasses and goggles.
  • Practice eye hygiene: always wash your hands before you insert or remove your contact lenses, and follow proper cleaning and storage guidelines for your contacts, as recommended by your eye doctor. Even if you don’t wear contacts, avoid rubbing your eyes – because fingers are exposed to a lot of dirt and bacteria, which can be transferred easily to your eyes. Also, don’t forget to remove eye makeup nightly to avoid a build-up of bacteria in your ocular area.
  • Don’t dry out your eyes: make sure to stay adequately hydrated by drinking enough water, and direct air vents in your car and home towards your torso, instead of blowing directly at your eyes.

When in doubt – book an eye exam near you

If you notice any new symptoms and don’t know what they are, such as the sudden appearance of many floaters and/or light flashes in your peripheral vision, call your eye doctor immediately. These could be signs of a retinal tear or detachment, which requires urgent eye care to prevent lasting vision damage. Or if you experience blurry vision, pain, or any oozing discharge, you may have an eye infection that needs medical treatment. Any time you aren’t sure about a symptom, it’s best to practice caution and contact a center for eye care near you.

Is School Work Causing Computer Vision Syndrome in Your Child?

Eye health tips for students from our Las Vegas eye doctor

The start of fall means back-to-school for kids of all ages – and our team at Yesnick Vision Center wishes everyone a smooth and successful return to the classroom!

When your child enters school after a summer of outdoor fun, many of the summer’s vision hazards are left behind. Yet, that doesn’t mean all eye health risks are eliminated! Nowadays, the majority of learning is computer based – exposing students’ eyes to the pain and dangers of blue light and computer vision syndrome. Fortunately, a variety of helpful devices and smartphone apps are available to block blue light and keep your child’s vision safe and comfortable.

To help you safeguard your child’s vision for the upcoming semesters and the long term of life, our Las Vegas optometrist explains all about computer vision syndrome and how to prevent it.

Symptoms of computer vision syndrome

It’s smart to familiarize yourself with the signs of computer vision syndrome. If your child complains about any of these common symptoms, you can help prevent any lasting vision damage by booking an eye exam with our Las Vegas eye doctor near you:

  • Eye irritation and redness
  • Neck, shoulder and back pain
  • Blurry vision
  • Dry eyes, due to reduced blinking
  • Headaches

Basics of blue light

Students spend endless hours in front of digital screens, be it a computer monitor, tablet, or smartphone. There is homework to be done, research to be conducted, texting with friends, and movies and gaming during downtime. All of this screen time exposes your child’s eyes to blue light.

Many research studies have demonstrated that flickering blue light – the shortest, highest-energy wavelength of visible light – can lead to tired eyes, headaches, and blurry vision. Additionally, blue light can disrupt the sleep/wake cycle, causing sleep deprivation and all the physical and mental health problems associated with it. As for your child’s future eye health, blue light may also be linked to the later development of macular degeneration and retinal damage.

How to avoid computer vision syndrome

Our Las Vegas eye doctor shares the following ways to block blue light and protect against computer vision syndrome:

  • Computer glasses, eyeglasses lenses treated with a blue-light blocking coating, and contact lenses with built-in blue light protection are all effective ways to optimize visual comfort when working in front of a screen. These optics reduce eye strain and prevent hazardous blue-light radiation from entering the eyes.
  • Practice the 20-20-20 rule; pause every 20 minutes to gaze at an object that’s 20 feet away for 20 seconds. This simple behavior gives eyes a chance to rest from the intensity of the computer or smartphone screen, preventing eye fatigue.
  • Prescription glasses can be helpful when using a computer for long periods – even for students who don’t generally need prescription eyewear. A weak prescription can take the stress off of your child’s eyes, decreasing fatigue and increasing their ability to concentrate. Our Las Vegas optometrist will perform a personalized eye exam to determine the most suitable prescription.
  • Moisturize vision with eye drops. One of the most common symptoms of computer vision syndrome is dry eyes, namely because people forget to blink frequently enough. Equip your child with a bottle of preservative-free artificial tears eye drops (available over the counter) and remind them to blink!
  • Blue light filters can be installed on a computer, smartphone, and all digital screens to minimize exposure to blue. A range of helpful free apps are also available for download.
  • Limit screen time for your child each day, or encourage breaks at least once an hour. Typically, the degree of discomfort from computer vision syndrome is in direct proportion with the amount of time your child spends viewing digital screens.
  • Set the proper screen distance. Younger children (elementary school) should view their computer at a half-arm’s length away from their eyes, just below eye level. Kids in middle school and high school should sit about 20 – 28 inches from the screen, with the top of the screen at eye level.
